摘要：
The activities of Dy in Dy-Fe alloys with Dy concentrations ranging from (7.0 to 89) at% were determined at (1273 to 1573) K by measuring the ion current of the vapor of Dy in equilibrium with Dy-Fe melts, Dy2Fe17 + gamma Fe, etc. The standard Gibbs energy of formation of Dy2Fe17, Dy6Fe23, DyFe3, and DyFe2 were calculated from the activities of Dy obtained from these measurements.
